Weight loss precautions: weight loss: control staple food and limit sweets. If the original food intake is large, the staple food for three meals a day can be reduced by 50 grams. Gradually control the staple food at about 250 ~ 300g g. Wheat, rice and some miscellaneous grains can be selected as staple foods, but we must strictly limit the amount of food we eat and develop the habit of eating seven or eight times full. Try to eat less or not to eat too much starch and very sweet food, such as sweet potato, potato, lotus root starch, jam, honey, candy, candied fruit, malt extract, fruit juice candy and so on. Some foods containing too much fat, such as peanuts, walnuts, sesame seeds and various animal oils, butter, fried foods, etc., should also be controlled. Non-staple food can use lean meat, fish, eggs, bean products and vegetables and fruits with low sugar content.
